What does the render() method do in ReactJS?

Answer:

It takes input data which is a Component and returns a string to display.e.g.

<div id="mountNode"></div>

var CustomMessage = React.createClass({
render: function() {
return <div>Hello {this.props.name}</div>;
}
});

ReactDOM.render(<CustomMessage name="DNF" />, mountNode);


Output
----------

Hello DNF
